COUPLING.

SPECIFICATION formingpart of Letters Patent No. 256,280, dated April 11,1882. Application filed December 31, 188i. (No model.)

To all whom it may concern:

Be it known that I,FELIX BROWN, a citizen of which the following is aspecification.

This invention"relates to couplings for shafting and the like; and itconsists in a recessed bodyprovided with clampsandapairofwedges, eachhaving at one end a screw-bolt adapted to receive a tightening-nut, allconstructed and arranged as hereinafter more fully described.

' This invention is illustrated in the accompanying drawings, in whichFigure 1 is a section in the plane'zz, Fig. 3. Fig. 2 is a section inthe plane 3 y,-Fig. 3. Fig. 3 is a section in the plane m w, Fig. l.

' Similar lettersindicate corresponding parts.

In the drawings, the letterA designates the body of the coupling.

(l is the opening for the shafting or axis, which opening is bounded onone side by the body A, while on its other side it is bounded by theclamps B B. These clamps rest with one of their sides against shouldersor recesses in the body A. The free ends of the clamps B are subjectedto the action of wedges E, which wedges are provided with orform part ofscrew-boltsl),onto which nutsFcanbescrewed. These nuts F rest againstthe faces of the body A and against the outer faces of the clamps B, asshown in 2, and by tightening the nuts F the wedges E are caused topress against the free ends of the clamps B, thus diminishing the sizeof the opening 0 and firmly clamping the ends ofshafting or of axlesthat may be placed in said opening. By this arrangement the clamps B, ofwhich there are two, are also prevented from falling out of the bodyAorfrom becoming displaced. By unscrewing the nuts F the clamps B andall the parts within the body A can be removed from out of the same, andif any of the parts should break or.

become worn out they can thus be readily replaced.

I am aware that couplings have been made provided with clamps inconnection with tightening-screws-as, for example, in the patent ofCharlton, No. 126,183, of April 30, 1872; but

the disadvantage of these couplings is that it the clamps should becomeworn or broken they cannot be taken out and replaced by newones, becausethese clamps form part of the. body. By my device, on the contrary,.anypart which is broken or worn can be removed and replaced in a very shorttime, saving labor and expense.

What I claim as new, and desire to secure by Letters Patent, is

-1. The combination, in a coupling, of a recessed body with the clampsB, located within the same, and the devices for tightening up theclamps, consisting each of a wedge having atone end a screw-threadedbolt adapted to receive the tightening-nut, substantially as described.

2. The combination, in a coupling, of the recessed body A, with theclamps B, each having a portion of one of its sides resting against ashoulder within the said body, and the devices for tightening uptheclamps, each consisting of a wedge applied against one side of theclamps and having at one end a screwthreaded bolt, whereon thetightening-nut is fitted, substantially as described.

' In testimony whereof I have hereunto set my hand and seal in thepresence of two subscribing witnesses.
